The 4manner of driving the conveyor is :is follows: Referringparticularly to F igs. 6 and?, it will be noted thut there is provided amotor 27 which issupported upon the axle 2 und upon n counter s'huft 28.The armature'shuft 29 of this motor is provided with n gear wheel 30,which in turn meshes with :t geur wheel 31 loosely mounted upon thevaxle' 2.

'lhis chain 38 also engages a.sproc et 39 carried on a Sha-ft 40, .Which latter is also supported inbrackets 41 carried on the underside of the frame. Referring to Fig. 9it will be notedthat this shaft 40 is also provided with n worm 42 andthis worm,

meshes with e worm Wheel 48 carried by one of the cornerv shafts of theconveyor. This shaft has been designated 44 and its upper end isprovided with a drive sprocket 45', over which the conveyer chain 11passes. sprocket wheels 4 6 of the fore, loosely mounted on their rctive shafts. Therefore,f, whenever it is esired to set the conveyer inoperation, the switch` geven-nin the current to themotor 27, is closed.hould it hedesired to rotate the, conveyer in the opposite' direction,the cur- `rent to the motor muy be reversed so that this motor`itselfwill run in u reverse direction.

These two slide'rods are, controlled by means ofhandles (i5 and (36 respectively, these handles being mounted on eachside of the machine as a whole, so that control may be effected when theoperator happens to be on either side of the machine, These handles 65and 66 are pivotcd at their lower ends to the frame plates and theirconnection with the slide rods is a pivotal mounting intermediate theirends.

bers (il) which in roalilyiorm alhird frame thil control is forthemining machine itself. As is we ll known, a mining machine compriseswhat 1s known as a stationary member and a movable or cutter member andit is upon these channel' members 69 that the so-called stationarymember is rigidlyy mounted to enable the kerfcuttng machine as a wholeto be moved forward by sliding the channel members 69 over the rollers68. This stationary member comprise-s an angle iron structure 7 0 heldproperly spaced by means of tie plates 71 and a front piece formed ofmembers/'72 and 73, it bein to the latter that the caster 26 is secured.`he angle iron framework is provided on its under surface with a pairofracks 74 by means of which the cutter member is lnoved forward. This'cutter member comprises a pair of side channels 75 of a well knownconstruct-ion which are securely held spaced at their forward ends 85 bymeans of a pair of opposed plates 76 be tween which sprocket wheels 77are rota* tably journaled` The channel members 75 forni a guide for thecutter chain 78 and it is over the sprocket 77 that this cutter chain 90passes. This cutter member also includes a central bar 79 which. at itsforward end slides between the front plates 72 and 73 of the stationarymember and which carries the driving or operating mechanism at its rearend. This driving mechanism comprises a motor support plate 80 rigidlyse cured lo the central bar 79 by means 'of a holt shown at S1 andfurther provided With laterally extending ears 82 which slide upon 100the. upper surface of the angle stationary member T0, Upon this motorsupport plate S0, the motor S3 is supported and the arma lure shaft. ofthis motor carries a pinion 84. This latter pinion meshes with a spurgear4 105 Hf rigidly mount-ed on a shqfl Sli which is suitably journaledin the motor support framework and which shaft also provided with bevelpinions 87 and 88 and n. worm 89. 'lhe pinion 87 meshes with a bevelgear90, 110 mounted upon a shaft 91 which carries n. worm 92 atts lowerend. This latter worin meshes with a worm wheel 93 loosely mounted-on ashaft 94 and it is thisshaft on which mount-ed. The worm wheel 93 115itself is provided with a clutch face 9 5 de t signed to cooperate, witha ,clutch collar 96 itself slidably keyed on the shaft 94 and opt cratedby means of a yoke leper 97. 0n each end of the .shaft 94 there isnionnted a spur 120 pinion 9S which cooperates with one of the racks 74and. therefore, when the clutch col lar 96 4is shifted to a position ofengageend, which worm is desi 100 which carries a worm 101 at its othered to mesh with a worm wheel 102 also s idably mounted on the shaft 94and this worm wheel is further provided with a clutch face 103. Thus,when the clutch 4collar is moved to engage the e'lutch face 103, it isout of engagement withfft'li clutch face 95 and, therefore, the wormwheel 93 is idle on this shaft, while the worm wheel 102 is rigidlyconnected with the same. Because of the driving connection between theshaft 86 and this 'worm wheel through the medium of the worm 89, wormwheel 99 and Worm 101, the shaft 94. will be rotated in a directionreverse to that previously described, thus causing a rota- Ititan in thereverse direction of the spur pinions 98, whi in turn causes aretraction of the machine. To drive the cutter chains the shaft 86 isprovided with the bevel pinion 88 whichmeshes with a bevel gear 104which latter is in turn mounted on a shaft 105 which carries a drivingsprocket 106 for these cutter chains,

F rom the foregoing description, taken in connection with. theaccompanying Sheets of drawings, it will be apparent that I haveprovided a machine of some considerable utility. This follows from thefact that all of the necessary operations may be performed by the samemachine and the several functions performed by this machine are allaccomplished by a common movement. Thus, when it is desired to use thekerf cutting structure, the conveyerstructure is swung about itspivot 2to elevate the forward extension 4 to a position suilieient to permitthe extension of the kerf cutting structure within the channel members69. After this has.been accomplished, the cutter member is extended andit may cat its way into the coal face, or it may be fully extendedbefore hand a'nd the entire machine moved forward to Iforce its `entryinto the coal face. After this, the traction wheels are driven so thatone rotates in one direction and the other in the opposite direction,where by aout across the entire face is effected. The kerf cuttingstructure is then retracted and the conve er Structure lowered to assumethe positlon `shown in Fig. 1 andv after' the coal has been' broken downin any desired manner, a further swee of this conveyor structure acrossthe floor' o'llowing'r theV same motion as' thatv used for the kerfcutting structure, or, in other` words., driving one of the tractionwheels in one direction and the other inthe other direction, will sweepthe mine door to clear it ofA the `broken down coal.
